The Bogle-Chandler Mystery is recognised as one of the most baffling cold cases in the annals of crime.

The victims, brilliant physicist Dr Gilbert Bogle and Mrs Margaret Chandler were found dead beside a picturesque river in Sydney, Australia. Investigators found no evidence to suggest how they had died. The bizarre manner in which the bodies were covered only added to the mystery. The police immediately suspected Margaret's husband, Geoffrey Chandler, as the killer. But despite drawing on the expertise of police and forensic agencies around the world, the coroner was unable to determine how the victims met their fate.

In his award-winning film and book on the case, the author presented new evidence, which provided a solution to the mystery. This new edition, brimming with photos and original documents, features the explosive testimony of a previously unknown witness to the deaths - a testimony that has thrust the case back onto the coroner's desk.

'This really is quite amazing! All I can say is that if what your new source says is true, then it pretty much means you've hit the nail on the head, and the mystery is finally solved, just over half a century after the event.' - Professor Jo Duflou, Chief Forensic Pathologist, University of Sydney

'An excellent read that for the first time tells the full story, aspects of which have baffled the best of scientific brains here and overseas.' - Viv Mahoney, Chief Toxicologist, Bogle Chandler Case
